Why is the medium frequency heating furnace used for forging heating?

In the forging workshop, the equipment we see is heating equipment and forging equipment, which are the necessary production equipment for the forging workshop. The heating equipment is often an intermediate frequency heating furnace. After the forging blank is heated in the intermediate frequency heating furnace, the temperature of the forging blank is raised to an appropriate temperature to improve the plastic deformation ability of the metal blank and improve the internal metal structure of the forging. Smaller forging equipment The raw metal can be deformed. The deformation resistance of forging blanks at high temperature is only 1/300 to 1/50 of that at room temperature. In addition, some metals or alloys are difficult to deform at room temperature and must be heated in an intermediate frequency heating furnace before forging. Therefore, processes including forging, steel rolling, hot stamping, drawing, etc. require the metal to be heated in an intermediate frequency heating furnace to obtain reliable plastic deformation at high temperature before processing.

The use of intermediate frequency heating furnaces for heating metal workpieces is widely used:

1. The intermediate frequency heating furnace is used for heating of steel plates and similar plates. The heating efficiency is high, the heating is uniform, the burning loss rate of the steel plate is low, and the heating temperature can be controlled, so that the intermediate frequency heating furnace is widely used for heating metal plates.

2. In the heating rolling or heat treatment of steel bars, due to the fast heating speed of the intermediate frequency heating furnace, good heat penetration performance and high degree of automation, rolling steel ball production lines, wear-resistant steel bar production lines, high-strength bolt production lines, round steel heat treatment production lines, petroleum The heat treatment production of steel pipes and so on came into being, and the intermediate frequency heating furnace became the main force of these production lines.

3. The medium frequency heating furnace is used for the forging diathermy equipment, and the control performance of the thyristor power supply is reliable. The intermediate frequency heating furnace has low power consumption, small burning loss, easy to start, stable operation, touch screen man-machine interface, sensitive operation, high reliability, strong anti-interference ability and convenient maintenance.
